A glob of very soft clay is dropped from above onto a digital scale. The clay sticks to the scale on impact. The experiment is then repeated, but instead of using the clay glob, a superball with identical mass is dropped from the same height onto the scale. Both the clay and the superball hit the scale 2.9s after they are dropped. Assume that the duration of the collision is the same in both cases and the force exerted by the scale on the clay and the force exerted by the scale on the superball are constant.

Required:
a. Sketch the graph of the superball's velocity vs. time, vball , from the instant it is dropped (t=0sec) until it bounces to its maximum height (t=6sec). Assume that the superball undergoes an elastic collision with the scale, and that the scale's recoil velocity is negligible. The light colored graph already present in the answer window is vclay (t).
b. Based on your graph, is the change in velocity of the superball during its collision with the scale greater than, less than, or equal to the change in velocity of the clay during its collision with the scale?
c. Is the force exerted by the scale on the superball greater than, less than, or equal to the force exerted by the scale on the clay?
